Stomata are found in the epidermis of aerial parts of the plant. Epidermis is the outermost protective covering of the plant organs and is made up of living cells which do not enclose intercellular spaces.
Stomata are numerous in leaves, fewer in stems and absent in the roots. In dorsiventral leaves stomata occur mostly on the lower epidermis however, are abundant on both the lower and upper epidermis in isobilateral leaves.
